Heating services across London
We look after gas boilers and central heating systems in homes, rented properties and small businesses across London, from annual servicing and breakdown repairs to complete new installations.
All our gas work is carried out by Gas Safe registered engineers (Register No: 567557). We explain what needs doing and agree it with you before any work starts.
Signs your heating needs attention
Call us if your boiler keeps losing pressure, shows a fault code or makes unusual noises, or if some radiators stay cold. Small problems are usually easier to fix early, before they turn into a breakdown.
Most manufacturers recommend a boiler service every 12 months, and it is often a condition of the warranty. A yearly service is also a good chance to spot problems before winter.

New combi, system and regular boilers, plus complete central heating installations, fitted safely and tidily.

What it is
We install new gas boilers and central heating systems, from a like-for-like boiler swap to a complete new system with radiators, pipework and heating controls. Every gas installation is carried out by a Gas Safe registered engineer.
When you need it
It may be time for a new boiler if yours keeps breaking down, spare parts are getting hard to find, your energy bills keep creeping up, or the boiler can no longer keep up with your home. Moving house, building an extension or converting a loft are also good moments to rethink your heating.
How we do it
We start by looking at your home, your hot water use and your existing system, then recommend the right type and size of boiler. On installation day we protect your floors, remove the old boiler, fit and commission the new one, test the whole system, complete the Building Regulations notification and show you how to use the controls.
Boiler Servicing & Repair
Annual boiler servicing, breakdown repairs and maintenance to keep your heating and hot water running.

What it is
A boiler service is a thorough safety and performance check of your boiler. Our repair service finds and fixes the fault when your boiler stops working, leaks, loses pressure or starts making unusual noises.
When you need it
Most manufacturers recommend a service every 12 months, and it is often a condition of the boiler's warranty. Call us straight away if you have no heating or hot water, the pressure keeps dropping or the boiler is showing a fault code.
How we do it
During a service we inspect the boiler and flue, check the gas pressure and combustion, clean key parts where needed and confirm that everything is working safely. For a repair, we diagnose the fault, explain what needs doing before we start, and then fix it.
Power Flushing
A deep clean for your central heating system that removes sludge and rust to bring back heat and efficiency.
Show details
Hide details
What it is
Power flushing pushes water and cleaning chemicals through your radiators and pipework at a high flow rate to clear out the sludge, rust and scale that build up over time.
When you need it
Typical signs are radiators that are cold at the bottom or have cold patches, a noisy boiler or pump, rooms that take a long time to warm up, or dark water when you bleed a radiator. It is also worth doing before a new boiler is connected to an older system.
How we do it
We connect a power flushing machine to your heating system and flush each radiator in turn. We then refill the system with clean water and add an inhibitor to help protect it against future corrosion.

Heating questions
What should I do if I have no heating or hot water?
Check that the boiler has power, the thermostat is turned up and the pressure gauge is in the range shown in your boiler manual. If the boiler is showing a fault code or still won't work, call us on +44 7727 290739 – we're available 24/7.
How often should my boiler be serviced?
Once a year. Most manufacturers recommend a service every 12 months, and it is often a condition of the boiler's warranty.
How do I know if I need a new boiler?
It may be time for a new boiler if yours keeps breaking down, spare parts are hard to find or your energy bills keep rising. We'll look at your system and tell you whether a repair or a replacement makes more sense.
What is a power flush?
A deep clean of your central heating system. Water and cleaning chemicals are pushed through the radiators and pipework at a high flow rate to clear out sludge, rust and scale.
